In addition, the phone's Ultra Snapshot function enables the user to be camera-ready 1.2 seconds after double-clicking the down volume button while in locked mode, instead of spending time trying to unlock the screen.

The "Voice Photo" function takes photos accompanied by 10-second audio clips for users to upload photos with special audio expressions on a social media platforms.

In addition to camera improvements, Huawei's Image Signal Processor (ISP) allows the smartphone to control functions that mimic those found in professional digital SLRs, including autofocus, white balance, and noise reduction, for optimized photos under any conditions. Users can also select the focus and exposure metering function with one touch.

At 6.5mm slim, Ascend P7 is one of the slimmest 4G LTE smartphones in the market. Its 5-inch full HD screen (445ppi and 16:9 aspect ratio) is further enhanced with Corning Gorilla Glass 3, which has been also used as a rear cover.

The phone is powered by a 2500 mAh lithium polymer battery and a proprietary battery saving technology. In addition, the power saving management function enables users to save battery by switching off any applications running in the background that are consuming unnecessary power. The power-saving mode enables Ascend P7 to adopt the most suitable use of power when it is running on less than 10 percent of the total battery. When enabled, the screen will dim and only the basic functions of the phone will remain activated, including voice calls and the contact page. It will also stretch the remaining 10 percent of battery power to last 24 hours on standby.
